The ‘two‐colour lattice gas model’ is applied to the analysis of shear layers between two parallel flows with different velocities U 1 and U 2 . Two cases, (a) U 1 = 0.4, U 2 = 0.2 and (b) U 1 = 0.4, U 2 = 0.0, are calculated and compared with the theoretical solutions. We obtain good agreement between theory and calculations in the velocity profiles of the shear layers. It is found that this model can simulate complicated physical phenomena of shear layers at the microscopic level.
